The “Voice” coach, 36, has asked a judge for an emergency protection order to stop David Otunga’s “continued efforts to place [her] in a bad light and tarnish her reputation,” according to court papers obtained by Page Six via The Blast on Thursday.

She alleged her ex-fiancé “or a third party on his behalf” leaked “false” information to the press that he was awarded full custody of their 8-year-old son, David Otunga Jr., and also asked that the court find him in contempt for allegedly violating a confidentiality agreement.

“[Otunga]’s and his agents’ ongoing effort to place [her] in a false light and creative negative news is harmful to the parties’ child and to [her] career,” she argued.

She added, “Without [her] career, the family would suffer irreparable injury financially as she is primary supporting the family due to [Otunga]’s voluntary underemployment.”
